IMPROVEMENT IN LAMP-SHADE HOLDERS.

I Specification forming part of Letters Patent No. 189,102, dated April3, 1877; application filed February 26, 1877.

To all whom it may concern:

' Be itknown that I, HIRAM L. I'VES, of Troy, in the county ofRensselaer and State of New York, have invented a new and ImprovedLamp-Shade Holder, of which the following is a specification Theaccompanying drawing represents a vertical central section of myimproved lampshade holder.

This invention relates to an improved illuinina-ting shade-holder forlamps, by which different-sized shades may be used, and a more perfectcombustion and brighter light without the use of a chimney produced.

The invention will first be described in connectiou with the drawing,and then pointed out in the claims.

In the drawing, A represents a lamp-shade holder that is made ofinverted conical shape and of transparent glass, the angle of the sidesbeing' so arranged that the rays of light are reflected from the shadeat the opposite side of holder in the most favorable manner to producethe greatest amount of light.

The holder A is provided with a widening base part, B, that is providedwith a scalloped bottom edge and suitable perforations a.

A dome-shaped glass section, 0, extends .from the base B upward into theholder, ex-

tending around and above the burner, whereby the air is carried directlyfrom the lower draft-holes to the flame, to produce the more perfectcombustion of the vapors. The holder and dome-section may be made in onepiece or in separate pieces, as desired.

The upper circumference of the shade-holder A is provided with twoflanges, D, of

The flanges admit the use of different-sized shades, which are seatedthereon, forming an intimately-closing joint between the shade andholder. The flame burns with a bright and steady light without the useof a chimney, as it receives a direct air-supply through the bottomholes and interior dome-section, and as the holder and shade togetherform a chimney, and keep out any draft of air.

Having thus described my invention, I

claim as new and desire to secure'by' Letters Patent 1. A lamp-shadeholder of inverted conical shape, having two flanges at the uppercircumference, to admit the use of shades of different size,substantially as specified.

2. A lamp-shade holder of inverted conical I shape, and provided withtwo flanges, at the upper circumference of which the inner flange HIRAML, IVES.
